Guess these runflats really are nail magnets! I've picked up my second nail in my rear driver side tyre within 5 months of having the car... friggin annoying i must say!
strange thing is though i measured the tyre pressures this morning (cold) and its only lost about 1-2psi in pressure compared to my other tyres, yet my run flat warning came on last night. So im wondering is it really that sensitive, or is my nail an incidental finding and do i have another problem?

Also, i have access to an old tyre (same tyre) that had a nail in it, but when taken off it was discovered the nail had not gone all the way through. do you guys reckon its safe to reuse? there was never any pressure loss in this tyre.

Oh and can you guys recommend any one to fit the tyre? got my last one done at Beaurepair, and they scrapped the top inner edge of my wheel just where the tyre sits!

RFTs can be repaired and I'd be more than happy to repair and run with a repaired RFT. Of course touch wood I don't have to!

Do remember that any damage on or close to the sidewall isn't repairable. Plus if you are had low pressure and weren't sure for how long, don't repair either. In your case, I would definitely repair and I trust you won't notice a thing apart from a few extra $$s in your back pocket :smile:

Fully agree. I would even go as far as repair it myself as I have a puncture repair kit. Shouldn't be any different to a regular tyre. Provided of course, as mentioned you haven't damaged it by driving on it flat for too long/fast.

hey guys, it deff has not been running on low pressure as its only dropped a couple of psi. however the nail is pretty close to the side wall. whats the reasoning as to why you cant repair it if its close to the side wall?

My mate just came past this morning with a nail sticking out of his sidewall on his new R32..

These are just normal tryes ( NOT RF ) and he has to order a new tyre..

Sidewall flexes a lot more than the tread area. A hole in the tyre is very likely to have damaged some of the steel/nylon/etc reinforcement to the rubber. In the tread area that is not issue. On or near the sidewall, the constant defections each time the tyre goes around can cause the existing damaged steel beads to cause further damage which eventually may result in a rapid blowout when you least want it.

hey guys,
well few days after i first noticed the nail and it has lost no further pressure, granted i have not driven it since either.
anyway, im planning on changing it over for the tyre from my dad's car (only had a few thousand ks on it). The story with his was that he noticed a nail but no pressure loss. A guy at the bmw dealer sprayed some water over it and it seemed to bubble (dont know how reliable this test is though???) when my dad's tyre got changed the guy said the nail had not gone through, but didnt give a reason why it would then need to be changed. anyway we kept the tyre.
i've attached some photos, the first two show my tyre with the nail sticking out of it, and the second two show my dad's old tyre, its quite a small hole and i could not see any evidence of a hole on the inside side of the tyre...

That looks more like a bolt in the first two pics, and would have left quite a hole....and so close to the sidewall.... Whilst it might still be holding pressure, I'd expect it to lose pressure pretty bloody quickly if you remove the bolt! That tyre is now in heaven.

hmm... would you say the damage to the second tyre is close to the side wall?
my plan was to replace the tyre with my dad's old one assuming there was no increased risk of the tyre suddenly blowing out, and if it leaks then replace it... but if there is a increased risk of it blowing out id rather not take that risk...

Just spent the last 4 hours at the tyre shop! got there with my dad's old tyre and waited for them to swap them over. about an hour and a half later later they took off my tyre, and got my dad's old tyre out of my boot.... he's about to put it on and he says "cant put this on, the side wall is damaged". apparently when they remove a runflat from a wheel they damage the tyre in the process! so i asked them if they had any in stock... nope, so i had to order one, and since im busy the next two days i had to get them to courier it up from where ever they get them from, which cost an extra $100!. so another hour and a half - 2 hours later my tyre shows up, only tyre on the ute! guess thats where my $100 went. the rest is history...
Man i hate runflats!!!!! they're friggin expensive, you cant fix em, no one stocks them, and they have a strange attraction for sharp objects....
the guy at the tyre shop said i wouldnt be able to change to non runflats without changing the wheels... any truth to this?????

heres a photo of the ute which brought my tyre in, saved my car from being stuck in the tyre shop for the night!

The issue is that runflat tyres require a special type of wheel that allows them to be fitted. You cannot fit runflats on conventional wheels. On the other hand, there is absolutely no problem with fitting regular tyres on wheels that are able to take runflat tyres. I've had regular tyres on my MINI's original 16" rims for years and it coped no problem with road and track use.

BTW it is definitely possible to remove a runflat tyre and reuse it on another (runflat-capable) rim. Been there done that. If the tyre was damaged in the removal process, then that's due to incompetence and you should be due some compensation.
